حَدَّثَنَا حَجَّاجُ بْنُ مِنْهَالٍ، حَدَّثَنَا مُعْتَمِرُ بْنُ سُلَيْمَانَ، قَالَ سَمِعْتُ أَبِي قَالَ، حَدَّثَنَا أَبُو مِجْلَزٍ، عَنْ قَيْسِ بْنِ عُبَادٍ، عَنْ عَلِيِّ بْنِ أَبِي طَالِبٍ ـ رضى الله عنه ـ قَالَ أَنَا أَوَّلُ، مَنْ يَجْثُو بَيْنَ يَدَىِ الرَّحْمَنِ لِلْخُصُومَةِ يَوْمَ الْقِيَامَةِ‏.‏ قَالَ قَيْسٌ وَفِيهِمْ نَزَلَتْ ‏{‏هَذَانِ خَصْمَانِ اخْتَصَمُوا فِي رَبِّهِمْ‏}‏ قَالَ هُمُ الَّذِينَ بَارَزُوا يَوْمَ بَدْرٍ عَلِيٌّ وَحَمْزَةُ وَعُبَيْدَةُ وَشَيْبَةُ بْنُ رَبِيعَةَ وَعُتْبَةُ بْنُ رَبِيعَةَ وَالْوَلِيدُ بْنُ عُتْبَةَ‏.‏
